Description

Technical Field

[0001] The present invention relates to the technical field of automatic dimension detection, and particularly to an automatic foam aluminum dimension detection device. Background Art

[0002] Foam aluminum is a material made by adding specific additives to pure aluminum or aluminum alloy and through a foaming process. It combines the firmness of metal and the lightness of bubbles. This material has the advantages of low density, excellent impact absorption capacity, high temperature resistance, excellent fire resistance, corrosion resistance, sound insulation and noise reduction, low thermal conductivity, high electromagnetic shielding, good weather resistance, filtering ability, as well as being easy to process, install, having high forming accuracy, and being able to be surface painted.

[0003] In the current industry, the measurement of the size parameters of foam aluminum plates mainly relies on manual use of tools such as tape measures, calipers, or laser rangefinders. This not only takes time and effort, increasing the labor intensity, but also may lead to errors in the measurement results; especially in large-scale production, the number of plates to be inspected is numerous, which not only increases the production cost of the enterprise, but also may affect the production efficiency and the factory passing rate of the products.

[0004] In addition, the existing laser measurement equipment needs to pause the aluminum plate in position for measurement during use, and when measuring, it is also necessary to push the aluminum plate to the measurement position and ensure that the straight edge of the aluminum plate contacts the baffle. This process not only takes time, but also the paused aluminum plate will interfere with the conveying of subsequent aluminum plates.

[0005] Therefore, an automatic foam aluminum dimension detection device is needed. Summary of the Invention

[0010] Preferably, the inner sides of the lower ends of the double-headed groove rods are rotatably installed with fourth adjusting rods. The lower ends of the fourth adjusting rods are fixedly installed with fourth U-shaped seats. The lower ends of the fourth U-shaped seats are fixedly connected to the upper ends of the adjusting motors.

[0011] Preferably, a chute is formed from the outside to the inside of the rotating rod. The adjacent ends of the sliding rods are slidably installed inside the chute. Symmetrically rotating second motors are fixedly installed in the middle layer of the rotating rod. Second screw rods are fixedly installed on the output shafts of the second motors inside the chute. The second screw rods are rotationally and threadedly connected to the sliding rods.

[0012] By adopting the above technical solution, the second screw rod can be rotated under the action of the second motor. When the second screw rod rotates, the sliding rod can slide inside the chute.

[0013] Preferably, a U-shaped groove is formed at the lower end of the support rod. Symmetric driving springs are fixedly installed on the upper end surface inside the U-shaped groove. A sliding plate is fixedly installed at the lower ends of the driving springs.

[0014] Preferably, a limiting rod is fixedly installed on the outer side of the sliding plate. A second distance measuring instrument is fixedly installed on the upper end surface of the limiting rod. A third distance measuring instrument is fixedly installed on the outer side of the lower end of the support rod.

[0015] By adopting the above technical solution, the servo motor can rotate the fixedly connected conveying roller, and then drive the chain to rotate, so that multiple conveying rollers can rotate simultaneously, thereby enabling the foam aluminum plate to be conveyed.

[0016] Preferably, symmetric L-shaped support rods are fixedly installed at the front and rear ends of the installation and conveying frame. At the upper ends of the two horizontally arranged L-shaped support rods, a grooved rod is fixedly installed. A sliding table is slidably installed inside the grooved rod. The upper end of the sliding table is fixedly connected to the side adjacent to the opening of the U-shaped cover. A blocking plate is fixedly installed on the left side of the sliding table.

[0017] Preferably, L-shaped vertical plates are fixedly installed on the front and rear sides of the right end of the installation and conveying frame. Reset springs are fixedly installed on the upper left sides of the L-shaped vertical plates. The left sides of the reset springs are fixedly connected to the adjacent sliding tables.

[0018] Preferably, a first U-shaped seat is fixedly installed on the inner side of the upper part of the L-shaped support rod. A first adjusting rod is rotatably installed inside the opening of the first U-shaped seat. The inner end of the first adjusting rod is rotatably installed with a second adjusting rod. A support spring is fixedly installed between the first adjusting rod and the second adjusting rod. The outer side of the inner end of the second adjusting rod is rotatably installed with a second U-shaped seat. An L-shaped mounting rod is fixedly installed inside the second U-shaped seat. Rollers are rotatably installed horizontally and evenly inside the L-shaped mounting rod. The front and back surfaces of the foam aluminum plate are attached to the circumferential surface of the rollers.

[0019] By adopting the above technical solution, under the action of the support spring, the first adjusting rod and the second adjusting rod can rotate, and then the L-shaped mounting rod can move in distance, so as to complete the clamping operation of the foam aluminum plate without affecting the conveying operation of the aluminum plate, thus facilitating the subsequent width measurement operation.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, under the action of the U-shaped cover, the adjusting motor can drive the rotating rod to rotate. After the rotation is completed, the second motor is started, and the sliding rod can drive the distance measuring rod to move. After the movement, the sliding plate can be attached to both sides of the foam aluminum plate. Then, under the action of the first distance measuring instrument and the distance measuring rod, the length test can be completed. Secondly, under the action of the second distance measuring instrument, the closest distance between the circumferential surfaces of the front and rear rollers can be tested, so as to complete the width test of the foam aluminum plate. Finally, the third distance measuring instrument can test the distance between the conveying roller. Since the emitted laser point of the third distance measuring instrument and the lower end surface of the rotating rod are in a horizontal state, the thickness of the foam aluminum plate can be obtained, and thus the full-size measurement can be completed at one time, saving the time of manual measurement.

[0021] 2. In the process of the operation of the present invention, when the foam aluminum plate slides, since the inner side of the sliding plate is in contact with it, at this time, when the foam aluminum plate moves, it will drive the sliding rod and the rotating rod to move synchronously, and further can drive the U-shaped cover to move synchronously, so that the position of the foam aluminum plate will not pause, and thus the subsequent feeding and material conveying will not be affected.

[0022] 3. In the present invention, under the action of the L-shaped mounting rod and the roller, the foam aluminum plate can always be in the central position, thereby ensuring smooth conveying and guaranteeing the accuracy of measurement during the conveying process.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 11 , the present invention provides a technical solution: An automatic foam aluminum size detection device includes an installed conveying rack 1. Symmetric first grooves 2 are provided on the front and rear inner sides of the upper end of the installed conveying rack 1. Among them, chains 4 are rotatably installed inside the two first grooves 2, and gears 6 are rotatably installed at equal intervals inside the chains 4. The outer sides of the gears 6 are rotatably installed inside the first grooves 2. Moreover, a conveying roller 5 is fixedly installed between two adjacent gears 6 in the front and back. The left end of the rear part of the installed conveying rack 1 is fixedly installed with a servo motor 3, as Figure 2 and Figure 3 shown.

[0027] During the use process, start the servo motor 3. The output shaft of the servo motor 3 will drive the fixedly connected gear 6 to rotate, and the gear 6 will drive the conveying roller 5 and the chain 4 to rotate synchronously. Therefore, under the action of the chain 4, all the gears 6 on the right side can be driven to rotate. Furthermore, driven by the gear 6, the conveying roller 5 can be rotated in one direction. At this time, place the foam aluminum plate 42 on the circumferential surface of the conveying roller 5, and the foam aluminum plate 42 can be moved from the right side to the left side, as Figure 1 shown.

[0028] Then, L-shaped support rods 7 are symmetrically and fixedly installed on the front and rear side surfaces of the installation conveyor frame 1. The upper inner sides of the L-shaped support rods 7 are fixedly installed with first U-shaped seats 8 of U-shaped structures. The openings of the first U-shaped seats 8 face inwards. And, first adjusting rods 9 are rotatably installed inside the first U-shaped seats 8. The inner ends of the first adjusting rods 9 away from the first U-shaped seats 8 are rotatably installed with second adjusting rods 10, as Figure 5 shown. It should be noted that the end of the first adjusting rod 9 away from the first U-shaped seat 8 is a U-shaped opening. Therefore, the outer end of the second adjusting rod 10 can be rotatably installed inside it.

[0029] Then, the first adjusting rod 9 and the second adjusting rod 10 form a triangular structure. And, a support spring 11 is fixedly installed between the inner sides of the first adjusting rod 9 and the second adjusting rod 10. Under the action of the support spring 11, the first adjusting rod 9 and the second adjusting rod 10 can change their angles and reset.

[0030] The inner end of the second adjusting rod 10 is fixedly installed with a second U-shaped seat 12. The inner sides of the two second U-shaped seats 12 in the horizontal direction are jointly fixedly installed with an L-shaped installation rod 13, as Figure 4 shown. And, the right side of the L-shaped installation rod 13 is an outward arc structure for facilitating the entry of the foam aluminum plate 42. And, rollers 14 are rotatably installed in the upper part of the L-shaped installation rod 13. The circumferential surface of the rollers 14 can be in contact with the horizontal side surface of the foam aluminum plate 42. During the conveying process, friction can be reduced, facilitating conveying, so as to measure the subsequent width.

[0031] It should be noted that during use, there is a certain distance between the lower end of the roller 14 and the circumferential surface of the conveying roller 5, so as to avoid collisions. Therefore, during use, the elastic force of the support spring 11 is in an equal state, and then the foam aluminum plate 42 can be in the center position of the conveying line.

[0032] Secondly, the elastic force of the support spring 11 cannot be too large, which is likely to cause the foam aluminum plate 42 to be clamped, resulting in the situation of being unable to convey. Therefore, during use, the support spring 11 needs to be debugged multiple times to make the L-shaped installation rod 13 driven by it in a proper state, which can not only allow the foam aluminum plate 42 to slide, but also make the rollers 14 in contact with the horizontal surface of the foam aluminum plate 42.

[0033] During the use process, under the action of the supporting spring 11, the first adjusting rod 9 and the second adjusting rod 10 can rotate, and the degree of the included angle between the two can be changed. Secondly, the second adjusting rod 10 drives the second U-shaped seat 12 to push the L-shaped mounting rod 13 to move, so as to complete the limiting operation of the foam aluminum plate 42.

[0034] Then, a groove rod 15 is fixedly installed transversely at the tops of the two horizontal L-shaped support rods 7, a sliding table 16 is slidably installed inside the groove rod 15, and a blocking plate 161 is fixedly installed on the left side of the sliding table 16. Because during the subsequent use process, when the sliding table 16 resets, it is prevented from continuing to slide to the right.

[0035] After that, L-shaped vertical plates 18 are fixedly installed on both the front and rear sides of the right end of the installation conveyor 1, a return spring 19 is fixedly installed on the upper left side of each L-shaped vertical plate 18, and the left side of the return spring 19 is fixedly connected to the right end of the sliding table 16. During the subsequent operation process, after the restriction on the foam aluminum plate 42 is released, under the restriction of the return spring 19, the sliding table 16 will slide by itself under the action of the return spring 19 and then reset. A U-shaped cover 17 is fixedly installed on the upper end surfaces of the front and rear two sliding tables 16, as Figure 6 shown.

[0036] After that, a first distance measuring instrument 20 is fixedly installed at the center position of the upper end surface of the outer side of the U-shaped cover 17. The first distance measuring instrument 20 emits laser light to both the left and right sides, and the distance of the laser light is the length of the subsequent foam aluminum plate 42. It should be noted that the length of the first distance measuring instrument 20 is the distance from the left side to the rightmost side.

[0037] Two third U-shaped seats 21 are symmetrically and transversely fixedly installed on the upper end surface inside the U-shaped cover 17. Third adjusting rods 22 are rotatably installed on the inner sides of the lower ends of the third U-shaped seats 21, and double-headed groove rods 23 are rotatably installed on the lower ends of the third adjusting rods 22, as Figure 7 shown. Fourth adjusting rods 26 are rotatably installed on the inner sides of the lower ends of the double-headed groove rods 23. In addition, a first motor 24 is fixedly installed on the outer side surface of the left double-headed groove rod 23. A first screw rod 25 is fixedly installed on the output shaft of the first motor 24, and the right end of the first screw rod 25 is threadedly rotatably connected to the right double-headed groove rod 23.

[0038] During the use process, when the first motor 24 is started, the output shaft of the first motor 24 drives the first screw rod 25 to rotate. At this time, under the action of the first screw rod 25, the distance between the left and right double-headed groove rods 23 can be increased or decreased, so as to change the inclination angles of the third adjusting rods 22 and the fourth adjusting rods 26, and further be able to drive the subsequent adjusting motor 28 to adjust the up and down height.

[0039] On the outer sides of the lower ends of the fourth adjusting rods 26, fourth U-shaped seats 27 are rotatably installed, and the lower ends of the fourth U-shaped seats 27 are fixedly connected to the tops of the adjusting motors 28, as Figure 7 shown.

[0040] Then, on the output shaft of the adjusting motor 28, a rotating rod 29 is fixedly installed. Chutes 30 are opened at both ends of the rotating rod 29 to the inside. And symmetrically fixedly installed in the central inner layer of the rotating rod 29 are second motors 31. It should be noted that the two second motors 31 are located on both sides of the output shaft of the adjusting motor 28, as Figure 8 shown. On the output shaft of the second motor 31, a second screw rod 32 is fixedly installed. And on the circumferential surface of the second screw rod 32, inside the chute 30, a sliding rod 33 is threadedly rotated and installed. The sliding rod 33 is slidably installed inside the chute 30.

[0041] Therefore, during use, when the second motor 31 is started, the output shaft of the second motor 31 will drive the second screw rod 32 to rotate. When the second screw rod 32 rotates, it can make the sliding rod 33 horizontally slide inside the chute 30.

[0042] One outer end of the sliding rod 33 is fixedly installed with a vertically arranged support rod 34. And on the top of the support rod 34, a ranging rod 35 is rotatably installed. It should be noted that during subsequent operations, a sliding plate 38 is provided at the lower end of the support rod 34, and the inner side surface of the sliding plate 38 is attached to the adjacent longitudinal surface of the foam aluminum plate 42. Therefore, the inner side surfaces of the ranging rod 35 and the sliding plate 38 are in the same plane. Therefore, when the first rangefinder 20 emits laser light, under the action of the left and right ranging rods 35, the length of the laser light can be directly obtained, and then the length of the foam aluminum plate 42 can be obtained.

[0043] Then, at the position where the ranging rod 35 is rotatably connected to the support rod 34, a commonly used return spring on the market is adopted. Therefore, during use, the sliding rod 33 will enter the inside of the U-shaped cover 17, and at this time, under the action of the return spring, the ranging rod 35 can be rotated. When the sliding rod 33 slides out of the inside of the U-shaped cover 17, the ranging rod 35 can be in a vertical state under the action of the return spring to avoid obstruction.

[0044] Then, a U-shaped groove 36 is opened at the lower end of the support rod 34. On the upper end surface inside the U-shaped groove 36, symmetrically arranged driving springs 37 are fixedly installed. The lower ends of the driving springs 37 are fixedly connected to the sliding plate 38. The outer lower end of the sliding plate 38 is fixedly installed with a limiting rod 39. The lower end surface of the limiting rod 39 is in a horizontal state and is used to contact the circumferential surface of the conveying roller 5.

[0045] During the use process, the sliding rod 33 will drive the support rod 34 to move downward synchronously. The support rod 34 will drive the driving spring 37 to move downward synchronously. The driving spring 37 will drive the sliding plate 38, and the sliding plate 38 will drive the limiting rod 39 to move downward synchronously. At this time, the limiting rod 39 contacts the circumferential surface of the conveying roller 5, and then the sliding plate 38 can compress the driving spring 37. At this time, it should be noted that under the action of the second motor 31, the inner side surface of the sliding plate 38 fits the longitudinal surface of the foam aluminum plate 42.

[0046] At this time, second distance measuring instruments 40 are fixedly installed on the upper end surfaces of the front and rear limiting rods 39, and a third distance measuring instrument 41 is fixedly installed on the lower left end surface of the support rod 34, as Figure 9 shown.

[0047] During the use process, the second distance measuring instrument 40 will emit laser for distance measurement front and back, and the emitted laser will irradiate on the circumferential surface of the roller 14. It should be noted that the minimum distance between the front and rear rollers 14 is the width of the foam aluminum plate 42, because during the operation process, the lateral surface of the foam aluminum plate 42 contacts the minimum distance between the outer circumferential surfaces of the front and rear rollers 14, as Figure 10 shown. Therefore, the length of the laser emitted by the second distance measuring instrument 40 is the width of the foam aluminum plate 42.

[0048] Then, the third distance measuring instrument 41 emits laser downward. After the laser irradiates on the circumferential surface of the conveying roller 5, it is the follow-up of the foam aluminum plate 42, as Figure 11 shown. Therefore, under the action of the above-mentioned first distance measuring instrument 20, second distance measuring instrument 40 and third distance measuring instrument 41, the full-size data of the foam aluminum plate 42 pair can be obtained, and then the output can be sent to the computer terminal.

[0049] Working principle: First, place the foam aluminum plate 42 on the circumferential surface of the conveying roller 5, start the servo motor 3, and the output shaft of the servo motor 3 drives the fixedly connected gear 6 to rotate. The gear 6 drives the conveying roller 5 to rotate, and at the same time the gear 6 drives the chain 4 to rotate. Then, under the action of the chain 4, all the gears 6 are driven to rotate, so that the conveying rollers 5 rotate synchronously, and then the foam aluminum plate 42 can be moved.

[0050] Then, under the action of the support spring 11, the first adjusting rod 9 and the second adjusting rod 10 are rotated, so that the second adjusting rod 10 can drive the second U-shaped seat 12 to move. The second U-shaped seat 12 pushes the L-shaped mounting rod 13 to move, so that the roller 14 can limit the foam aluminum plate 42.

[0051] Start the first distance measuring instrument 20, second distance measuring instrument 40 and third distance measuring instrument 41.

[0052] Start the first motor 24. The output shaft of the first motor 24 drives the first screw rod 25 to rotate. When the first screw rod 25 rotates, it causes the third adjusting rod 22 and the fourth adjusting rod 26 to rotate, thereby enabling the adjusting motor 28 to move downward. After moving to an appropriate height, stop the operation.

[0053] Then, the adjusting motor 28 drives the rotating rod 29 to rotate. The rotating rod 29 is in a horizontal state. Start the second motor 31. The output shaft of the second motor 31 drives the second screw rod 32 to rotate, thereby causing the sliding rod 33 to slide, and the sliding rod 33 drives the support rod 34 to move.

[0054] After the support rod 34 moves to both sides of the foam aluminum plate 42, start the first motor 24 again to make the adjusting motor 28 move downward so that the lower end surface of the limiting rod 39 fits the circumferential surface of the conveying roller 5. At this time, start the second motor 31 again to make the inner side surface of the sliding plate 38 fit the longitudinal surface of the foam aluminum plate 42. At this time, the ranging rod 35 is in a vertical state, and the laser emitted by the first rangefinder 20 contacts the ranging rod 35, thereby obtaining the length of the foam aluminum plate 42.

[0055] Then, the second rangefinder 40 emits lasers forward and backward and irradiates on the circumferential surface of the roller 14 to obtain the width. The third rangefinder 41 emits a laser downward and irradiates on the circumferential surface of the conveying roller 5 to obtain the thickness. It should be noted that since the lower end surface of the rotating rod 29 fits the upper end surface of the foam aluminum plate 42, the position where the third rangefinder 41 emits the laser is in a horizontal state with the lower end surface of the rotating rod 29.

[0056] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
